A 19-year-old London man has been charged with assault and sexual assault following altercations Wednesday evening involving two teenage girls.

Police were called to the Wavell Street and Vancouver Street area at approximately 9:45 p.m. after they received a complaint that a teenage girl had been assaulted by a man on a bicycle.

While they were searching the area for the suspect, police received a second complaint from another teenage girl who said she was sexually assaulted by a male who fit the same description.

Police searched for a suspect described as a white man, 16-19 years old with a thin build and short dark brown hair. He was seen wearing a red t-shirt, black or grey plaid shorts and riding a BMX-style bicycle.

Police and members of the Sexual Assault and Child Abuse section are still investigating.
